Multiple Streams Add #23

Open freesig opened 5 years ago

freesig commented 5 years ago

Streams need to add to buffers. So they each CPAL stream is mixed into the single ASIO stream.

[x] Zero silence buffers so you can add
[x] Add each output together
[ ] ~~Add each input together~~

I thought this is working but I made a demo that combines two outputs and it sounds different on Wasapi vs Asio I'm not sure if this is due to adding or to the formats being off. I think the formats might be off because even a single beep sounds a bit different.

Todo

[ ] Write an example that plays a recorded wav through each channel then all together. I think this will make it easy to hear if it's not right.
[ ] Run the above example on ASIO and Wasapi and record the output
[ ] Write an example that records each channel separate and then all channels.
[ ] Try the above example on Wasapi and ASIO
[ ] Write an example that records multiple streams and check that they are the same.
